IC, VM; Restart of the accelerator 
|
08h45 Start-up modulator, laser, magnets
09h38 Shutter Laser Linac is yellow. Tuning off the gun operation key does not change it to the red. Need help.
09h55 HV is on |
|
IC, VM; Restart of the accelerator
|
11h20 Try to restart the accelerator. Start-up modulator, laser, fridge, chillers
Problem, with all magnets control All DS are in FAULT state. Help is needed.
It is solved. |
|
IC, VM; Restart of the accelerator
|
08h35 Start-up modulator (it was already on standby), laser, magnets, cycling.
As yesterday there is a problem with the MPS to start the machine. We are trying to investigate whether it is related to the vacuum or something
else. |
|
IC, VM; Ring working point studies
|
07h35 Start-up modulator (does not go to standby), laser, magnets, cycling.
9h50 HT ON
~10h30 Electricity cut |
|
IC, VM; Restart of the accelerator
|
09h35 Start-up modulator
09h52 Start the fridge
09h55 Start chillers |
|
IC, VM; Restart of the accelerator
|
08h26 Start-up modulator, laser, fridge, chillers, cycling
09h31 Low SF6 pressure => JN helped
11h HV ON. We do not see the RF signals, even the baselines (RedPitaya). |
|
IC, VM; Restart of the accelerator
|
07h30 Start-up modulator, laser, fridge, chillers, cycling remotly
Vacuum in the FPC is still ~1e-7 (sometimes goes to ~7-8e-8);
No RF signals. The same problem. |

|
08h25 Start ThomX: Modulator, Frigo, cycling all magnets
08h30 Start chillers
10h00 HV is 'On' |
|
IC, VK, VM, JN; 6x
|
8h50 Start of the modumator and all subsystems
PC client 1 was frozen => we restarted
10h20 HV on 1215 V |
|
IC, VK, VM;
|
11h05 Start ThomX
11h50 BPM02-Libera04 wiring has been checked: 'OK'
12h20 HV is 'ON' 1215 V |
|
IC, VK, JN; ring studies 13x
|
8h50 Start of the modumator and all subsystems
Beam studies.
Orbit Correction. |
|
IC, HG, RC, DN, JM; Test of the new receipt from BMAD Isol = 242 A 13x
|
8h55: mise en chauffe (modulateur, frigo/chillers, laser, cyclage)
10h20 HV ON
Start with the receipt nominal. problem with the RF gun laser camera. Solved. |
|
IC, HG, JNC; Restart of the accelerator
|
02/06/2026
~15h30 Starting all system
16h Start up of the modulator, laser, magnets |
|
IC, DN, RC, HG, ME; Improve ring for X-rays 7x
|
Goal: Vertical orbit and angle at the IP with I3 and I4 X-ray signals
8h55 Switch ON the modulator and all the machine
Camera SST2 : impossible de changer le temps d'expo |
IC; RE: Test cyclage aimants
|
I have decresed the Imax to 8 A and loaded the new cycling curves
RI-C1/PS/QP.06 and RI-C2/PS/QP.02: normally cycling with Imax 8 A , finish without error => PS to be checked for Imax >8 A (nominal
10 A |
|
IC; Ring studies
|
08h56 Warm-up ThomX: Modulator, Laser, Fridge
Chillers were started, cycling all magnets.
Low SF6 pressure. |
|
IC; Ring studies
|
9h40: mise en chauffe (chillers/frigo, modulateur, cyclage)
HV ON
The ICT signal (GUN) is frozen. Need help to restart it. Use the BPM SpSum instead. |

10h30 : mise en chauffe (frigo/chillers, modulateur, laser, cyclage)
All rondes are broken, THOMX key is turned. What is the reason of this intervention?, There is nobody around. Jean-Noel came and helped
to solve the problems. |
